Abstract
Aim
It is the aim of this paper to present data on the survival of restorations in premolar teeth by analysis of the time to re-intervention on the restorations and time to extraction of the restored tooth, and to discuss the factors which may influence this.
Methods
A data set was established, consisting of General Dental Services (GDS) patients, this being obtained from all records for adults (aged 18 or over at date of acceptance) in the GDS of England and Wales between 1990 and 2006. The data consist of items obtained from the payment claims submitted by GDS dentists to the Dental Practice Board (DPB) in Eastbourne, Sussex, UK. This study examined the recorded intervals between placing a restoration in a premolar tooth and re-intervention on the tooth, and the time to extraction of the restored tooth.
Results
Data for more than three million different patients and more than 25 million courses of treatment were included in the analysis. Included were all records for adults (aged 18 or over at date of acceptance). In total, 3,591,372 restorations involving premolar teeth were included in the analysis. With regard to time to re-intervention, 42% of restorations had survived at 15 years, and with regard to time to extraction of the restored tooth, cumulative survival was 82%.
Conclusions
Overall, crowns placed on premolar teeth perform best to re-intervention after 15 years, but worst when the time to extraction of the restored tooth is examined. Factors influencing restoration longevity in premolar teeth include: age of patient, patient's treatment need, and age of dentist.
